I disagree with OP. You cannot abstract after two or three dupes because you don't even know what you have or need yet. Let it breathe, let it stink for a bit

I disagree with OP. You cannot abstract after two or three dupes because you don't even know what you have or need yet. Let it breathe, let it stink for a bit - THEN make an informed decision about what to refactor and abstract. You're just jerking off otherwise, and I hate working with code that's been abstracted early for no reason.
